Dynamic Analysis of Stick-Slip and Bit Bounce in Oilwell Drillstring

Drilling process consisting of drag bits which are used over drilling boreholes concerning generation along with research about oil and gas regularly undergo against caustic vibrations. As mentioned, vibrations will be able to cause the drag bit along with drillstring various breakdown concerning equipments. This project, a non-linear design concerning rotational and axial motions of drillstring plus bit act suggested. Furthermore, dynamics concerning two drive complexes considering translational along with rotational motions regarding drillstring is being advised. Regarding mentioned model, translational along with rotating motions concerning drag bit are reached in the process of result regarding total dynamic action. The consequences concerning numerous viable criteria covering dynamic action are considered including objective in producing an undisturbed drilling. Using appropriate selection concerning operational criteria can help in minimizing the consequences regarding bit-bounce also stick-slip. It is anticipated to aid lower time lost in drilling operation along with costs sustained because of caustic vibrations
